Question

Derive v=u +at & s=ut+1/2at2, where symbols have their usual meanings​

Answer 1

Answer:

(a) Suppose a body has an initial velocity 'u' and a uniform acceleration 'a' for time 't' so that its final velocity becomes 'v'. Let the distance travelled by the body in this time be 's'. The distance travelled by a moving body in time 't' can be found out by considering its average velocity. Since the initial velocity of the body is 'u' and its final velocity is 'v', the average velocity is given by

Average velocity =

2

Initial velocity + Final velocity

That is, Average velocity =

2

u+v
